Digital Modulation Techniques
DEFINITION: Modulation is the addition of information (or the signal) to an electronic or optical signal carrier. Modulation can be applied to direct current (mainly by turning it on and off), to alternating current, and to optical signals. One can think of blanket waving as a form of modulation used in smoke signal transmission (the carrier being a steady stream of smoke). Morse code, invented for telegraphy

MODULATION TECHNIQUES DEFINITION (continued): … and still used in amateur radio, uses a binary (two-state) digital code similar to the code used bymodern computers. For most of radio and telecommunication today, the carrier is alternating current (AC) in a given range of frequencies. Common modulation methods include:Amplitude modulation (AM), in which the voltage applied to the carrier is varied over timeFrequency modulation (FM), in which the frequency of the carrier waveform is varied in small but meaningful amountsPhase modulation (PM), in which the natural flow of the alternating current waveform is delayed temporarily These are … Modulation Techniques definition sponsored by SearchNetworking.com, powered by WhatIs.com an online computer dictionary
